The thing is that we don't know.
All of these rotational models using gravity do not match conditions we measure.
Such as the air pressure at the poles and equator should be different. They are not, how is that possible?

So, "modern science" just sweeps this under the rug.

DON'T LOOK HERE

My personal thoughts are that everything belong to a rotational system acts like it is standing still. Or, that all the matter has the same rotational vector applied to it.

This seems to hold up when working with super-fluids.
(like super-conductors, but fluids)
The rotational friction becomes less that zero and the fluid contracts.
Just freaking annoying... throws Einstein and Newton out the window, so don't look for this in any text books.
